Bracci universali per interfaccia con microregolazione B-Tech BT8390-VESA400MAF/B

System X Universal Interface Arms with Micro-Adjustment (VESA 400) provide a compact, secure solution for mounting medium to large screens on horizontal System X rails. Designed for videowalls and multi-screen setups, these black interface arms support displays up to 70" and a maximum load of 50 kg per the source text, while product data lists a 70 kg capacity — confirm load requirement before installation. The universal design fits most videowall screens and allows both landscape and portrait orientations with a minimal mounted depth of 85 mm for a near-wall finish.

Advantages

The arms offer tool-less micro-adjustment for precise, seamless display alignment and lateral adjustment so position arms anywhere along the rail. A simple ‘hook-on’ installation and included mounting hardware reduce installation time. Safety screws are provided to help prevent unauthorised removal of screens. The universal, modular design is compatible with most screens and supports flexible multi-screen configurations.

• Videowalls and multi-screen video installations

• Retail display walls and signage
• Projects requiring landscape or portrait mounting

How to use

Fit the interface arms onto System X horizontal mounting rails by sliding the arms to the desired lateral position and hanging the display using the hook-on feature.

Ensure the display weight and VESA pattern match the arm specifications and follow rail manufacturer instructions for overall system assembly.

Recommendations

Confirm the correct load capacity (50 kg vs 70 kg) for your specific screens before installation; adhere to VESA 400 compatibility and follow System X rail load limits and installation guidelines to ensure safe, stable mounting.
